## Long description

The ACS ACM39U‑Y3 smart card USB interface adapter is a compact reader module designed for contact smart and memory cards. Compliant with ISO 7816 Parts 1–3 and supporting Class A/B/C (5 V, 3 V, 1.8 V), the adapter handles both T=0 and T=1 communication protocols and provides a USB 1.1 (Full Speed) interface with a maximum smart card read/write speed of 600 Kbps. The unit measures 82×70×10 mm and is supplied in a black and green enclosure. Built around the ACR39 core and modern microchip technology, the ACM39U‑Y3 is intended for secure access control, card programming, authentication and payment terminal integration in embedded and desktop environments.
Advantages
The ACM39U‑Y3 delivers PC/SC and CCID compatibility for broad driver support across Windows, Linux and Mac OS, and includes Android integration for versions 3.1 and later. Its support for ISO 7816 Class A, B and C cards and both T=0 and T=1 protocols makes it suitable for a wide range of smart card types, including memory and microprocessor cards.

How to use
Install the device by connecting the ACM39U‑Y3 to a USB port on the host system; operating system drivers that support PC/SC and CCID will enable the reader without additional configuration on most modern platforms. Insert a compatible contact smart card into the reader until it seats firmly; the reader will negotiate voltage and protocol (Class A/B/C and T=0/T=1) automatically. Use standard smart card middleware or application software to send APDU commands for card programming, authentication or transaction processing. For embedded integration, mount the module according to your system’s mechanical and electrical design guidelines and ensure USB power and data lines meet the host requirements.
Usage recommendations
For reliable operation, use genuine contact smart cards compliant with ISO 7816, avoid excessive insertion force, and protect the connector from dust and moisture. When integrating into payment or e-banking solutions, follow relevant security and certification requirements and test the device lifecycle to validate the specified insertion cycle durability.
